Internship - Backend Developer for AI Applications

About Us

We are a Machine Learning and Computer Vision startup founded in 2020, headquartered in Dublin, Ireland, with an AI Lab in Milan, Italy.

Our expertise spans Machine Learning and Generative AI for financial services and Computer Vision for life sciences.

At Gemmo AI, we build custom AI solutions that combine automation with human insight. We use a modular approach: first we explore the highest-impact opportunities, then we design and deploy tailored solutions, and finally we help improve and maintain them over time.

We believe in responsible, pragmatic AI: systems that integrate into real workflows, provide measurable value, and remain under your control.

About The Role

We are looking for a backend developer to join our team and help integrate our models and solutions into our clients’ cloud infrastructures.

In this role, you will be responsible for co-designing, building and maintaining CRUD APIs, launching and orchestrating Machine Learning inference pipelines, and deploying the solution on the cloud.

You will collaborate closely with UI/UX designers, frontend developers and Machine Learning engineers, ensuring that AI components integrate into end-to-end solutions.

Compensation

• Compensation during internship: 800€/month;
• Up to 22k€ RAL for contract after successful internship;
